I've always wanted to get into systems but time was a major barrier to entry. Generative AI basically blew all my excuses out of the water - it does most of the initial work. I just tweak.

I think I posted the stats for the NVDA bol band system. They were good....but of course they were - the stock has been a multi year monster and probably will continue to be. That said - it's definitely in law of large numbers territory now and analysts are expecting decelerating earnings either later this year or the year after (I forget which) as competition ramps up. Every big winner eventually gets whacked back down to normie range -  APPL has taken a few long breaks over the years, GOOG, AMZN,TSLA, MSFT (why do you think they call it softie?), etc - no one escapes the eventual fall from cult stock status.
